It's possible. I went completely mental on my bf last week! Got my feelings hurt over him getting a Facebook account (of all things! ). I don't know if that "triggered" me or if he caught me at the verge of a manic episode......all I remember is becoming enraged, spewing things out of my mouth that I KNEW were hurtful to him, but I couldn't stop myself. The more I tried to hold in the hurt & anger-the worse my outburst became! It was PHYSICALLY CAUSING ME PAIN trying to hold back my words! It was as if I didn't get it all out, my emotions were strong enough to kill me. I mean I had a every cell of my body inflamed with the fires of HELL! I was even snapping at people I wasn't even mad at. I was even rationalizing things in my head while in the middle of it all. Asking myself things like-why is this bothering me so much? Is this REALLY what you want to do? Am I sure I want to end this relationship over fb? Am I going to be sorry for this when I finally calm down? Does he hate me now? I COULD NOT TALK MYSELF DOWN. I HONESTLY though my family was going to surely have me committed again. He almost left, but I mustered up the nerve to ask him to stay. To my surprise, he wasn't even mad at me the next day. But I did admit to him that night that I needed to make an apt. with my dr. and I did.
